Principles of Operation
Modified Transient Plane Source Technique


The C-Therm TCi Thermal Conductivity Analyzer employs the Modified Transient Plane Source (MTPS) technique in characterizing the thermal conductivity and effusivity of materials. It employs a one-sided, interfacial heat reflectance sensor that applies a momentary constant heat source to the sample. Typically, the measurement pulse is between 1 to 3 seconds. Thermal conductivity and effusivity are measured directly, providing a detailed overview of the heat transfer properties of the sample material.

TCi - THERMAL CONDUCTIVITY ANALYZER
 
 
C-Therm’s patented sensor technology makes thermal conductivity simpler and more accessible to measure. There is simply no faster or easier way to measure thermal conductivity and effusivity.

With the C-Therm TCi there is no complex regression analysis necessary as with other transient methods. No special sample preparation is required and there is no need to measure additional sample material properties such as heat capacity.

The TCi is provided with one versatile sensor for testing all types of materials; including solids, liquids, powders and pastes. A second sensor can be added for increased capacity.

The testing procedure is noninvasive; samples remain unaltered and reusable. The system offers users exceptional versatility in being able to operate in a variety of environments, including thermal chambers, high pressure vessels and glove boxes. Fast and accurate testing made easy!
 
 
DiL - HIGH PRECISION DILATOMETERS
 
 
Pushrod dilatometry is a method for characterizing dimensional changes of a material as a function of temperature. The measurement may be performed across a temperature range (e.g. from 800° to 1,600°C), or a specific controlled temperature program to mimic industrial processes, firing regimes, or a material’s operating environment. The coefficient of thermal expansion (α) is defined as the degree of expansion (ΔL) divided by the change in temperature (ΔT).

A precise understanding of thermal expansion behaviour provides crucial insight into firing processes, the influence of additives, reaction kinetics and other important aspects of how materials respond to environmental changes. Typical applications include: the determination of the coefficient of thermal expansion, annealing studies, determination of glass transition point, softening point, densification, kinetics and sintering studies.

C-Therm dilatometers offer high resolution and stability across a broad measurement range. With unparalleled ease-of-use, high adaptability, and modular design, C-Therm dilatometers offer researchers a robust cost-effective solution to their characterization needs.

Conforms to all major standard test methods for dilatometry, including ASTM E228.
